To all whomit may concern.' f

Be it known that we, EDWARD H. LANIER and FRANK K. DnmsnAcI-I, citizens of the United States, residing at Cincinnati, Hamilton county, State of Ohio, have invented certain new and useful Improvements in Machines for Forming and Baking Hollow Pastry Forms, of wluch the following is a speci cation.

The subjecty matterb of the present invention hollow pastry, articles, being especially adapted for the manufacture of ice cream cones.

.15` In the accompanying drawings, y

detail section through an'extracting core;

i Flg. 6"is a sectional view of a portion of n the mold carrier, on an enlarged scale;

Fig. 7 is a detaiLview of one of the lnolds in open position;

Fig. 8 is a detail view device; and J Fig.9 is a view of a the molds.

Referring to the drawings, the machine comprises a series of molds and an endless carrier which supports a series of forming cores and extends partially about the mold carrier, the several molds'in which are each `adapted to receive one of the cores during a portion of the travel thereof.` In the emodiment of ,the invention" illustrated the molds are supported in a drum-like body lmounted on a horizontal shaft or rod 1, the molds being arranged in two series about the periphery ofsaid body and the entire series being nclosed, except at one end, by a suitable casing or housing 2. This housing `or casing is interiorly heated, as by suitable of a core greasing device for greasing burners 3, the gas or other fuel for which is' supplied through a pipe 4.

is a machine for forming and baking run or section of carrler.

`cores 5 immediately The forming cores 5 are supported by an endless carrier that `axtends about'the mold drum and suitable supporting wheels 6 on a shaft 7 journaled in the frame work of the machine. The coresy 5 `are arranged in pairs corresponding to the molds, each pair being connected` and having laterally projecting p ins 8 that engage tl eteeth of the wheels 6- and the 'guides 9, 10 that are sup yorted by the frame vwork between said Wheel)s and the mold drum. The con 1s are so connected with the endless carrier as to be capable of rocking slightly relative to said carrier for a purpose to be hereinafter more particularly referred to.

The shaft 7 is drive a by suitable chain and sprocket gearing fron a motor 11 andas the endless core carri ar travels the series of molds Will be given a corres onding movem'ent, the several cores lentering the molds, traveling therein fox a sulicient distance through the housing o r casing 2 to `enable the mold contents to be p `operly baked, and being Withdrawn from the molds at the forward end of said housin The batter from v'hlch the articles are formed is contained in an elevated tank 12 from which it is supplied through a depending pipe 13 to an open top receptacle 14 supported on .the main frame beneath the upper the endless forming core This recepts cle 14 is preferably provided with double walls, or a water Jacket, so that the bitter therein Will be maintained at the desir ed temperature. Said vreceptacle being positioned close to the open Vend of the mold housin g 2, the batter therein f sof esy

is liable to be overhea ted unless some such cooling means as this is provided. yThe necessary batter for forming the cones is transferred from the receptacle 14 to the fer cup 15, which is supported from a shaft V16 v'suitably journaled on the frame of the machine and driven, as by chains 17 and ,suitable gearing, fron. the motor 11. e shown, this transfer cup is provided at'its sides With 4 upwardly extending arms 18 that are suitablyguided in 'xhe frame of the machine and one' of which has mounted thereon an adjustable stop 19. Said transfer cup is connected with'the lou er end of a link 20, the upper end` of lvvhicl. is bifurcated to extend on opposite sides ofa stud or pin 21 tiereover by a transy projecting laterally from a disk 22 on the end of shaft 16. A spring w 23 connects the pin 21 with a'pin adjacent thelower end of the ranged that when the cup 15 is in its lowest 4position it will be below the level of the batter in the receptacle 14 and as said cup is reciprocatedy a uniform coating of the cores 5 thereover is insured. The extent to which the coresover the transfer cup are coated with batter isi-determinedv by adjustmentof the screw stop 19 which, by contact with an abutment carried by the main frame, positively limits upward movement of the transfer cup 15. In case the extent of such movement is less than thatwhich would be imarted to the cup if the connection between 1t and the disk 22 was rigid, the pin 21 will there will be no danger move longitudinally of the bifurcation in the link 20, stretching the spring 2 3 slightly as said pin passes its highest position. By this means it is poible to make the articles produced by the machine of the desired length and avoid waste of batter. To maintain the desired quantity 'of receptacle 14, a suitableyvalve is provided adjacent the lower end of the battersupply duct or pipe 13, said valve being connected with an arm 24 that engages the supporting link 20 of the transfer cup. Therefore, as this cup is reciprocated the valve in the bat-l ter supply duct 13 will be automatically opened and closed whereby the necessary amount of batter will be constantly maintained in said receptacle.

To avoid any poss bility of interference between the cores cores are rocked sli position as they approach a position above said cup. As shown, each core is provided with a bent arm 25 that is adapted to be engaged by a guard 26 extendingk across the fguides, for the endless core carrier so that the cores will be carried into an inclined po-l sition in passing said guard as shown and of a core striking the outer side of the cup 15 as the latter rises from the rece tacle 14. When the' cores come directly a position to be coated, they are, as shown, in a substantially vertical osition. The arms 25 further coperate wit a springractuated guide 26* to tilt or rock the coated cores will come into proper slightly so that they alinin position with themoldsl as they are carrie along by the endless carrier. v

The molds are. referabl made in the form p articularl i lustra in Figs. 6 and 7 eac comprising two sections `pivotally connected adjacent their inner ends. Means are rovided whereby these sections of the m'ol are opened or closed by movement in adirection radially of the supporting drum.

As shown, each mold is provided with a link 20. The parts are so ar batter in the operate wit contained pastry from the forming core and means the drum to move the sections thereof intoi open or closed `include levers 34 fulcrumed on the frame f 5 and the batter transfer cup `15 means are 1provided whereby the g tly from their normal ove the transfer cup, or into f I core 5 is being through suitable guidesin the supporting drum, and ten'd through apertures in the peripheral wall of the drum, whereby, as the rod 27 and attached mold are inovedoutward, the sections of the mold will be opened and during inward movement of'said parts the mold will be closed. A knife edge '28* is provided about tl'ie mouth of the mold.

Meansare provided whereby the molds will be, automatically opened and closed as theI drum-like support therefor rotatesV and also for withdrawing the baked articles from the cores'after the latter and the forming Vcores have been separated. As the molds are preferably arranged in two parallel means for loosening the. baked. articles, open-A ing and closing the molds and withdrawing to be engaged by positively actin which the' mold is adjusted ra ially of relation. v The latter'ineans adjacent their lower ends and havin their upper ends guide ways through the pins 32 pass as the molds rotate/As shown, the lever 30 is so positioned that the pin'32 of each mold will coperate with a groove or guide on the inner -face of the lateral projection thereon'just rior to the beginning of the'movement of) Aseparation by which the forming core 5 is withdrawn from its coactin mold. As the pin 32 en ages said gui e on the lever 30 the mold Wil be positively slightly and this dinally of they contained core acts to loosen the baked article from the core, prior to with-inclinedguides 28 that eX- radially extending rod 27 that passes4 series about the periphery of the drum the t ach W ich moved radially inwardly slight movement longituthe beginning of the outward movement of the core by which it is separated from the mold. 'The contact between the pin 32 and the lateral arm of the' lever 30 Amaintains the mold tightly closed or locked while the withdrawn therefrom and retains the baked article in position therein. A stationary curved ide 33 is provided beyond the end of the ing the molds in closed position until the pins 32 thereof are engaged by the means provided for movingthem radiall outward and o ening the sections thereofi ever 30 for maintain- Sai levers 34 are connected with levers I 35, by which the extracting devices are carried. As these connections and the levers 34, 35 are duplicated on opposite sides of the machine only one set thereof will be herein particularly described.

The lever 35 is fulcrumed on the frame of the machine at an intermediate point in its length and above its fulcrum is connected with the lever 34 by alever-like link 36 fulcrumed at one end at 36"', on the lever 34 and provided adjacent its other end with a slot," that receives' a pin 35* on the lever 35. .A link 37 connects the' lower end of lever with a lever 38 that is fulcrumed 15 at 38 on the frame of-themachine and provided with a pin 38" which extends into a slot in the lever 36. V A suitable eccentric driven by the motor 11 is connected with 25 pin 35 is engaged 'in a notch or lateral extension at the inner end of the slot 36", in

the lever 36, so that` the two 1evers'34, 35

.are positively7 connectedandwill be simulta'iieously rocked outward (or to the left in 3o Eig. 1) by the action of the eccentric'40.y

l`hc extracting cores 42 are'mounted on a har or yrod 43 .that extends `through slots .formed in heads arranged at the upper ends 4 .of the levers 35, the rod being so supported a5 that it may have a limited movement in said {i1-:lots ani-,tchatthe cores'42 will be caused to @accurately aline with and readily enter-the .'opposvte molds when the machine is working. As shown, a guide bar 44 extends rear- 4o warrlly from each end of the rod 43 and is .provided with a slot 44l receiving apin'or stud mounted on the frame of the machine.

From the rod 43 depends a link 45 that at its lower end is pivotally connected with a lever-45, fulcrumed at 45", and having laterally projecting pins or studs 45 between which the eccentricconnecting rod 41 extends. j

These connections act to normally maintain the nextracting cores in such position that their points are directed toward the molds but means are provided for directing said cores downward so that the baked pastry articlesmay fall therefrom into a delivery chute 47. The rod 43 is revolubly mounted in the guide bars 44 and is provided at its ends with rocker arms 43, 43", extending, respectively, above and below the axis thereof. A spring 43 acts to hold the 30 arms 43, 43" in substantially vertical osition. As the lever 35 swings away rom the'molds the arm 43* strikes a stationary pin 48 which causes a rocking of the rod 43, `stretching the spring 43, as shown in Fig.

i5 4= so that the cores 42 are directed down-K ward and the baked articles can slip therefrom into the upper, open, end of the chute 47.

In Fig. l the parts are shown in the positions occupied when the extracting cores are within the alined molds and the ins 32 of the latter are near the lower en of the guides th zrefor' on the levers 34. As the A eccentric l0 moves the lever' 3 5 -forward, or away from the molds, the lever 34 is carried in the same direction, beingconnected thereto by reason of the pin 35a occupying the notch at the rear end of the slot 36". This outward movement of the mold enthe main :Frame by a' yielding link 49 which,l

when said lever has been .moved forward suicientli' far to bring the pin 38" on lever 38 (which through link 37 is moved rearwardly by lever 35) adjacent the rear-end of the slot in which it works, lifts 4theV lever 36 suflicie ntly to release the pin 35* therefrom. Diringthe further forward movement of rheupper end of lever 35"there-" fore the lever 34 (through the parts 3 7, 38, 36,) will De moved rearwardly 4to close the mold. A: the lever 35 approaches the limit of its fc rward movement the extracting cores will .berocked (by the arm 43* striking the pn 48) to permit the 'articles 'supported` thereon -to fall into the chute 47. On the return movement of the lever 35, thecores 2 are first restored to normal, sub.- stantiallyA horizontal, position by the spring 43 and troduced into the molds that have been brot ht into alinement therewith by rotation o the drum. During thismovement the lever 34 remains stationary the pins 38" a nd 35* move longitudinally ofthe slots in the link 36 into which they extend and at the `termination of ,such rearward movement the link 36 is given a slight "downward me vement about its -fulcrum 36",` owing to the connection of the link 49 there-` with so t'iiatthe pin 35l is caused to enter the notch at the rear end of the slot in which, it works.

The co:e extracting levers also suppor; i

means fol greasing the cores, 5. On eac the levers 35 is ivotally mounted at 55 a rockinghead and) in a suitable slotformed -in each ot? said. heads is arranged a projection' 50l from one of a pair of sectional bodies lin ed with felt or other suitable absorbent material and adapted to conform closely to the cores 5. As shown in Fig. 8

each of. said bodies includes two sections, 50, 51, co anectedby springs 52, 53,"so.tha1'l the will fit closely about one of the cores, sai bodies beingconnected together as by a rod 54. As thelevers 35 swing forward in Fig. 4 so as to surroun the alined cores 5. Each of the said heads on the levers is adapted to have a limited swinging move-- ment about its pivot 55 so that the greasing device is adapted to travel with the engaged core 5, while the lever 35 is turning about its pivot or there is relative movement between said lever andthe endless' core carrier. Such turning vmovement: of either of said heads on its lever 35 is limited by engagement of a pin or stud on the lever with the ends of a slot 55; and-a spring 55b is provided to return said parts to normal relation. On the return movement of the lever 35 the greasing devices are disengaged from the cores and returned to substantially the position shown in Fig. 1.

It is .occasionally desirable, particularly when first startin the machine, to a ply a certain amount o grease to the mol s.- To accomplish this the present machine includes a cone shaped body 60 of suitable ab- 'means for successively sorbent material and arranged to slip over each extracting core 42, being held in place by hooks 61 engaging the bar 43. The mold reasing devices can be readily detached from the cores 4250 as not to interfere with the actioniof said cores in extracting the baked cores from the-molds.
